Hi there, wonder if anyone can help
Have upgraded from 8.50 to 8.51 portable, and since then cannot open/read most e-books
error massage:
Cannot open ebook
I/O operation on closed file

have moved the whole thing from my portable external hard disk to a local one, still dosnt work,

have moved the e-book file to another installation of Caliber (on another computer) with 8.50 ver, and it is opening the book with no problems

Any Ideas anyone??

many thanks
